Let's divide 70373153 by 9
We're looking to find how many times 9 goes into 70373153.

On to step 1:
The number 9 fits into 7 0 times, leaving a remainder of 7.
Use 0 as the next digit of our solution. 
Result so far: 0.0
If we subtract 0 from 7, we get 7.
Include the next digit (0) from the dividend after 7, then repeat: 70 / 9

On to step 2:
If we divide 70 by 9, we get 7 and a remainder of 7.
Use 7 as the next digit of our solution. 
Result so far: 7.0
Subtract 63 from 70 to get 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 9

Let's proceed to step 3:
9 can be fit into 73 8 times, resulting in a remainder of 1.
Put 8 as the next digit of the answer. 
Result so far: 78.0
If we subtract 72 from 73, we get 1.
Fetch the next digit (7) from the dividend, attach it to 1 and continue: 17 / 9

Let's proceed to step 4:
If we divide 17 by 9, we get 1 and a remainder of 8.
Put 1 as the next digit of the answer. 
Result so far: 781.0
If we take 9 away from 17, we end up with 8.
Append the next digit (3) from the dividend to 8 and continue with: 83 / 9

On to step 5:
The number 9 fits into 83 9 times, leaving a remainder of 2.
Write down 9 as next digit of the result. 
Result so far: 7819.0
The remainder is 2 after subtracting 81 from 83.
Take the next digit (1) from the dividend and append it to 2, then repeat: 21 / 9

Advancing to step 6:
9 goes into 21 2 times with a remainder of 3.
The number 2 becomes the next digit in our result. 
Result so far: 78192.0
Subtract 18 from 21 to get 3.
Grab the next digit (5) from the dividend, add it to 3, then carry on: 35 / 9

Advancing to step 7:
If we divide 35 by 9, we get 3 and a remainder of 8.
The next digit of our result is 3. 
Result so far: 781923.0
If we subtract 27 from 35, we get 8.
Bring next digit (3) of the dividend behind the 8 and repeat the process: 83 / 9

Going ahead to step 8:
If we divide 83 by 9, we get 9 and a remainder of 2.
The next digit of our result is 9. 
Result so far: 7819239.0
If we take 81 away from 83, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Advancing to step 9:
If we divide 20 by 9, we get 2 and a remainder of 2.
Record the quotient 2 as the next digit in the result. 
Result so far: 7819239.2
If we take 18 away from 20, we end up with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

Moving on to step 10:
If we divide 20 by 9, we get 2 and a remainder of 2.
Put 2 as the next digit of the answer. 
Result so far: 7819239.22
Subtracting 18 from 20 leaves us with 2.
Since there are no more digits in the dividend, we add a zero to the remainder making it 20, and continue the process.

The final outcome is 7819239.22, with a leftover of 0.002.
